Abstract: A system for airborne remote sensing comprises an array of remote sensing devices configured for being towed by an aircraft. Each of the array of remote sensing devices is configured for lateral separation in flight, to provide a large coverage area than any of the array of remote sensing devices can cover by itself. Onboard electronics comprise sensors, such as a forward imaging infrared camera for capturing data in flight. By analyzing the data collected by the remote sensing system, various types of information can be generated, such as hydrocarbon leak detection.
